An object with a larger mass will have a larger heat capacity than an object with smaller mass of
-1
the material. Heat capacity is measured in Joules per degree Celsius (J °C ). The SI unit of heat

1.3 SPECIFIC HEAT CAPACITY

The specific heat capacity of a substance is the amount of heat energy required to increase the

-1 ° -
temperature of 1kg of the substance by 1 °C or 1 K. The SI unit for specific heat capacity is J kg C
1 or J kg K and the symbol is, c. The formula that relates heat energy, Q to specific heat capacity,
